Yii Framework get user data

Question

How can I get currently online user data with all the parameters from the database? Right now I get it's ID by using this:

echo Yii::$app->user->getId();

Can I reach other data somehow or do I have to create a function which gets all the information by the user ID?

Answer 1

You can access to all the identity values in this way

this for username

Yii::$app->user->identity->username

check for your User models for others attributes

(and your User model of course)

Answer 2

You can access the model of the currently logged in user with:

$user = Yii::$app->user->identity;

This will return either null (if the user is not logged in) or an instance of the identityClass you defined for the user component in your config. Ex:

'user' => [
    'identityClass' => 'app\models\User',
    'enableAutoLogin' => true,
],

So you can use it like any other model class and access it's attributes and/or methods. Just make sure you configure correctly the user component and the identityClass exists and can be accessed.

Answer 3

current user is:

Yii::$app->user->identity

it can be null, so check it before accessing fields
